Objective. The purpose of this study was to determine the effect of dietary intakes on nutritional indicators of patients on hemodialysis. Method. This study was carried out at the hemodialysis unit at the Ministry of Health, Ankara Hospital, from 2003-2004. Sixty-seven patients on regular hemodialysis were enrolled in the study. Nutritional status was assessed by biochemical parameters (urea, uric acid, creatinine, Na, K, Cl, Ca, P, alkaline phosphatase, SGOT, SGPT, cholesterol, total protein, albumin, hemoglobin, hematocrit) and anthropometric measurements (height, dry weight, body mass index), and dietary intakes were calculated. Results. In this study, the mean age of the patients was 45.3 +/- 13.49, and the duration of hemodialysis was 4.9 +/- 3.64 year. Dialysis time was 12.4 +/- 2.7 h/week. The ratio of individuals with BMI of 20 kg/m(2) or below this value was 19.4%. Blood hemoglobin and hematocrit levels were below than the recommended level. Mean serum urea (148.0 +/- 27.76 mg/dL) and creatinine (8.8 +/- 2.13 mg/dL) were found to be high, while a significant negative correlation was found between blood urea level and dietary fat (p < 0.01, r = -0.31). A significant positive correlation was found between vitamin B-1, vitamin B-6, folate, potassium, iron, and magnesium; between uric acid and vitamin D; between blood creatinine level and dietary vitamin B-1, vitamin B-6, folate, vitamin C, potassium, iron, magnesium; between blood potassium level and dietary vitamin C only; and between blood cholesterol level and dietary vitamin D only (p < 0.01).
